Abstract (en)

[origin: EP3435426A1] An n-type silicon substrate 1 is provided with a lightly doped region 11, and a first main surface-side highly doped region 12 having an n-type dopant concentration that is higher than that of the n-type lightly doped region 11. The first main surface-side highly doped region 12 is disposed between the n-type lightly doped region 11 and a p-type amorphous silicon layer 3.
